Is it really only Game 3? After 10 periods in the first two games of the Stanley Cup final, the Bruins and Blackhawks were in Boston on Sunday to prepare for Game 3. The best-of-seven series is tied at a game apiece. The Bruins evened it up Saturday night on Daniel Paille’s goal at 13:48 of the first overtime. That’s after the teams played 52:08 over three OTs on Wednesday in the series opener. Both teams are hoping to rest before getting back on the ice for Game 3 tonight ( 5 p.m., NBC Sports). Bruins coach Claude Julien said the hometown fans will help, but the team still has to play the game.
